The compressed package includes 3 reference program reports for comparative study and implementation guidance.

Detailed Documentation

The digital equalizer developed using MATLAB GUIDE serves as a powerful audio processing tool. It implements WAV file playback functionality with 8-band equalizer control, allowing users to customize audio quality through frequency band adjustments. The system features dual-display visualization showing both original and processed audio waveforms and frequency spectra, enabling real-time observation of audio modifications. The equalizer algorithm likely employs FIR/IIR filter banks for frequency band separation and gain adjustment. Key MATLAB functions involved may include audioread for file input, filter design functions (fir1, butter) for equalizer bands, and fft for spectral analysis. For additional reference, the compressed package contains 3 analogous program reports demonstrating different implementation approaches to digital equalizers, providing valuable learning resources for signal processing techniques and GUI development in MATLAB.
